Nov. 3, 1942. M, GUSBETH SAFETY LATCH SHAGKLE Filed March 28, 1940 Patented Nov. 3, 1942 UNITED STATES PATENT OFFICE SAFETY LATCH SHACKLE Martin Gusbeth, Bronx, N. Y.

Application March 28, 1940, Serial" No. 326,411

1 Claim.

This invention relates to devices for securing doors and like members when in a closed position.

An object of the invention is to provide a hasp or latching means combined with a keeper, and other positive locking means associated therewith whereby security may be obtained.

A further feature is in the provision of an adequate, yet simple, device which assures complete protection against unauthorized opening of a door provided with an embodiment of the invention.

Another purpose is to produce an efficient looking device, which may be used in connection with any preferred type of padlock, and further, having a seal which will unfailingly show evidence of tampering, should such occur.

These and analoguous objects are accomplished by the novel and practical construction, combination and arrangement of few and simple parts hereinafter described and illustrated in the annexed drawing constituting a material component of this disclosure, and in which:

Figure l is a perspective view of an applied embodiment of the invention, shown in a released or unlocked position.

Figure 2 is a front elevational view of the device, as seen in an engaged position.

Figure 3 is a top plan view of the same, showing the application of a padlock and also a common form of seal.

Referring in greater detail to the drawing, the numeral Ill designates either a conventional door, or one of the swinging elements of a double door, while ll denotes the other or hinged member.

Fixed on the member III, as by screws I2, is a keeper base plate l3, in which is rigidly secured a flat, forwardly extending, horizontal keeper I4, containing a narrow slot [5 in its base, adjacent the plate l3 and further provided with a circular opening 16, near its curved outer edge.

The other main member consists of a plate held by screws 2| to the swinging element II and fashioned at its outer edge, to present a hinge portion 22 through which passes a pin 23 engaged in loops 24 formed in the outer end of a plate 25.

This plate 25 contains a central elongated slot 26 near its opposite, free end, which is reduced and outturned as at 21; near the extremity is a small perforation 28 in register with the slot 26.

Pivoted on a pin 30 set midway in the length of the plate 25 is a latch 3| having in its underside a notch 32 defining the inner edge of a detent 33 engageable in the slot l5 of the keeper when the device is in applied position.

An extension 34 of the latch 3| is provided with a perforation 35, registrable with the corresponding perforation 28 in the plate 25. Riveted, as at 36; to the latch 3| isan angle 31 having an upstanding member 38 containing a circular opening 39, registerable with the corresponding opening IS in the keeper.

A padlock 4|], provided with a key 4|, has a bail 42 which can be passed through both openings I5 and 39, thereby to prevent raising the latch when the lock is used.

In addition a, wire 44 may be passed through the perforations 28 and 35, and the ends of the wire secured by a conventional lead seal 45, thereby clearly indicating if the latch shackle has been molested.

From the foregoing it will be seen that a safe and secure fastening means for doors has been disclosed in their best known embodiments.

However, it will be understood that such changes and modifications may be made as come within the purview of the claims hereto appended.

Having thus described the invention, what is claimed as new and sought to secure by Letters Patent, is:

In a self-contained safety door fastening shackle having a plate, one end fixed to the door closely adjacent the free edge thereof and a hinge at the opposite end, and a keeper plate fixed to the jamb of the door in register with the hinge carrying plate, a keeper set in a horizontal plane in said keeper plate, said keeper having a slot adjacent said plate and a circular opening spaced outwardly beyond the slot, a plate attached by said hinge to the first named plate and having an opening adapted to pass over said keeper, a latch plate pivotally mounted on the outer side of said hinged plate intermediate its length, a hook-shaped .detent integral with the lower edge of said latch plate adapted to enter the slot in said keeper, a member fixed on said latch plate to extend outwardly therefrom, said member having a circular opening registrable with the opening in said keeper whereby a padlock may secure the latch and keeper against separation and thereby maintain the hinged plate against movement relative to the keeper.
